Abstract

Se describe un procedimiento para la interconversión entre WS-1 y neo-WS-1 mediante calentamiento a una temperatura en una escala de 60 grados Celsius a 250 grados Celsius; el calentamiento puede llevarse a cabo en presencia de un catalizador de ácido; partiendo de WS-1 prácticamente puro (=98%), o mezclas de WS-1 y neo-WS.-1, puede obtenerse neo-WS-1 prácticamente puro (=98%); partiendo de neo-WS-1 prácticamente puro (=98%), o mezclas de WS-1 y neo-WS-1, puede obtenerse WS-1 prácticamente puro (=98%).
